tip

This page is part of multistep Testing a Custom Language Plugin tutorial.

Define the Test Data

Create the FindUsagesTestData.simple file in the testData directory.

# You are reading the ".properties" entry.
! The exclamation mark can also mark text as comments.
website = https://en.wikipedia.org/

language = English
# The backslash below tells the application to continue reading
# the value onto the next line.
message = Welcome to \
          Wikipedia!
# Add spaces to the key
<caret>key\ with\ spaces = This is the value that could be looked up with the key "key with spaces".
# Unicode
tab : \u0009

Create the test file FindUsagesTestData.java, which contains one embedded Simple Language prefix and key.

public class Test {
  public static void main(String[] args) {
    System.out.println("simple:key with spaces");
  }
}

Define a Test Method

Add the testFindUsages() method to the SimpleCodeInsightTest class previously defined. This test verifies the find usage functionality will identify the "key with spaces".

public void testFindUsages() {
  Collection<UsageInfo> usageInfos = myFixture.testFindUsages("FindUsagesTestData.simple", "FindUsagesTestData.java");
  assertEquals(1, usageInfos.size());
}

Run the Test

Run the test and make sure it's successful.
